Assessment of passenger benefits brought about by international airport projects

This study sets forth a method to calculate the passenger benefits of an international airport project and assesses the passenger benefits brought about by two international airport projects.An international airport project mainly increases the number of flights and the possibility of determining convenient timetables. It does not significantly decrease the flight time of international travel. Thus, the user benefits brought about by an international airport project cannot be expressed by the conventional concept of ‘traveling time’, which is the term generally used.In this study, the ‘Expected Value of Traveling Time’ and ‘Expected Value of Generalized Cost’ are presented as indexes to evaluate improvements in convenience brought about by international airport projects. The passenger benefits of two airport projects in Japan are measured by consumer surplus calculated from the demand function using these indexes.These indexes are accurately calculated taking into consideration factors such as scheduling connections between domestic and international transport, and so enable a grasp not only of reductions in flight time, but also of passenger benefits resulting from international airport projects, such as increases in the number of flights and reductions in the time required to make transfers during domestic travel.

行业协会发展与农产品供应链信息管理

本文通过地行业协会信息服务职能和农产品供应链信息管理的需求分析，认为随着农产品行业协会的进一步发展，其信息服务职能的发挥能够更好地满足农产品供应链信息管理的需求，因此提出建立以农产品行业协会为第三方组织的信息中心，协调农产品供应链中各环节之间的信息与利益，保障农产品供应链中信息畅通流动、利益分配均衡和消费者食品安全。为了充分发挥农产品行业协会的信息提供和信息协调职能，政府和社会相关各方需要在制度、技术和资金方面给予保障。     

中国企业内部控制评价系统研究

我国企业内部控制基本规范配套指引的发布,为我国企业内部控制体系中构建企业、注册会计师和有关监管部门三位一体的内外部监督评价体系目标的实现奠定了基础。考虑到我国的制度背景以及注册会计师对企业内部控制审计的局限性和可信度等因素,在企业内部控制披露和注册会计师内部控制审计披露的基础上,建立反映企业内部控制综合状况和水平的企业内部控制评价结果指标,由政府监管部门或外部非营利性机构实施对我国企业内部控制整体状况和各企业内部控制水平的评价是十分必要的。本文正是基于此环境和目标,结合国内外企业内部控制评价理论研究和实践状况,构建了我国企业内部控制评价系统。     

Fund size, limited attention and valuation of venture capital backed firms

This paper examines the effect of fund size on investee firm valuations in the venture capital market. We show a convex (U-shape) relationship between fund size and firm valuations. We further document that firm valuations are positively correlated to measures of limited attention. In addition, we show a concave (inverse U-shape) relationship between fund size and venture's performance measured as the probability of successful exits. Further, this relation is particularly strong when the pre-money valuation of the investment is high. Our findings hold across a wide range of robustness checks, including but not limited to sample selection and correction for unobserved company-level value drivers. Our findings support the notion that there is diseconomy of scale in the venture capital industry, which is partially due to the constraints from the quality and quantity of human capital when fund size grows.

基于小波神经网络的高阶CAPM实证研究

本文在传统CAPM的基础上,引入了一个高阶的CAPM。借助小波神经网络在非线性函数逼近方面的优势,使用上海证券交易所股票数据分别对二阶至四阶CAPM进行了实证分析。最终的研究结果表明:就上海股市而言,12只大盘股组合已经能够有效分散非系统风险,而12只小盘股不能充分化解非系统风险,存在所谓的规模效应;训练后的网络预测显示,高阶CAPM无论是在预测精度还是预测稳定性上都要明显优于传统的CAPM,在一个非系统风险得到充分分散的证券组合中,加入三阶矩的CAPM已经能够比较准确地把握风险资产的市场定价。
